7.4 Reducing Wall and Ceiling Clearances Safely
Note that the clearances of the appliance and the clearances of the pipes must be met
individually, meaning that the appliance cannot be installed closer to combustible materials
than the pipe allows.
However, it is possible to reduce the appliance's clearances by using either the heat shield
certified with the appliance or by following the instructions of this section. It is also possible
to reduce pipe clearances by using a heat shield certified with the pipe.
It is of
ten desirable to reduce
the minimum installation
clearances by placing the stove
closer to walls so the installation
t
akes up less floor space. You
can safely reduce the minimum
clearances by permanently
installing a shield between the
stove and combustible material.
The rules for safe shields can be
complicated, so read them
carefully and follow them
exactly. Note that there may be
minor regional differences in
clearance reduction rules so be
sure to check with your building
or fire inspector before
proceeding.
7.4.1 Shield Construction Rules
See Figure 7: Clearances for shield construction to match each letter to a clearance.
-
Adhesives used in shield construction must not ignite or lose adhesive qualities at
temperatures likely to be encountered.
-
Mounting hardware which extends from the shield surface into combustibles may be
used only at the edges of the shield.
-
Mounting hardware must allow full vertical ventilation.
A
Minimum clearance between the appliance top and an unshielded combustible ceiling:
1181 mm (46.5").
B
Shield extension above appliance: 500 mm (20").
C
Minimum space behind shield: 25 mm (1 in.). In Canada 21 mm (7/8").
